How to Begin:
     1. Elect a strong team leader ( Completely Self-managed! )
     2. Decide where your team will meet off campus to design and to possibly build your
        rocket.
     3. Delegate tasks WITH DUE DATES!
     4. Don’t procrastinate! DO IT!
     5. Exchange PHONE NUMBERS!!!!!!!!
     6. Exchange e-mail addresses!

Agreed Tasks For EACH TEAM MEMBER!
                            Print Name         Agreed Task(s) / Responsibility
      1. Team Member #1     ___________________ ______________________
      2. Team Member #2     ___________________ ______________________
      3. Team Member #3     ___________________ ______________________
      4. Team Member #4     ___________________ ______________________

Lab Days:
     1. There will be 2 lab days during the week to help your team to work on the rocket
        together. If the 2 lab days do not provide enough time for your team to complete
        the rocket, it is your TEAM RESPONSIBILITY to meet off-campus to complete the
        rocket.
     2. You must bring your own materials to the lab.
     3. You must store your materials IN YOUR LOCKER!
     4. Arrangements for the rocket itself to be stored in the lab can be made.


Proof of Rocket Stability:
      1. Each team MUST complete a computer simulation (software will be provided) that
          will calculate the safety and stability of your rocket design.
      2. Each team MUST have simulation results REVIEWED & APPROVED by the
          instructor.
      3. TEST LAUNCHES CANNOT BE MADE WITHOUT SUCCESSFUL SIMULATION
          RESULTS.

Rocket Launches:
     1. A limited amount of time is available for the launch of your rocket.
     2. One class period will be made available for teams to launch their rocket.
     3. Date for Rocket Launch will be __________________


Rocket Recovery Techniques:
     1. Floating-spin recovery
     2. Parachute recovery
                          Bottle Rocket Project                                        Page 4

BASIC PROCESS STEPS “CHECK-LIST”:

STEP 1.    Get Your Team ORGANIZED!
                  Who is your Team Leader
                  Who is responsible for what
                  Fill out the Index Card with your Team Name and Names of Team
                      members.
                  Exchange PHONE NUMBERS!!!!!!!!
                  Exchange e-mail addresses!

STEP 2.    Decide on the type of Recovery System your team will base the design of your rocket
           upon. Obtain a progress / acceptance stamp.

STEP 3.    Agree upon what materials EACH MEMBER must bring for your team to begin
           building your rocket. Be sure to have all team members understand that if one
           person fails to bring what they agreed to bring, your team will be unable to
           build during lab time and must then make-up the lost time outside of class!

STEP 4.    UNDERSTAND IN ADVANCE THAT YOU WILL NOT BE ALLOWED TO GO TO
           YOUR LOCKERS IF YOU FAILED TO BRING ANY MATERIALS TO LAB.
           You must plan ahead and be responsible for your actions / inactions.

STEP 5.    Establish a team hypothesis regarding your design goals and be
           sure to explain WHY. Obtain a progress / acceptance stamp.

STEP 6.    Make a DETAILED DRAWING of your team rocket. Be sure that all dimensions
           are shown. Use a PEN. Be NEAT. Obtain a progress / acceptance stamp.

STEP 7.    Build your rocket.

STEP 8.    Determine the C.G. (center of gravity) of your completed rocket. Draw the required
           symbol that identifies the C.G. of your rocket.
           Obtain a progress / acceptance stamp.

STEP 9.    Complete the “Rocket Stability Questionnaire”.
           Obtain a progress / acceptance stamp BEFORE using the computer.

STEP 10.   Enter the data from your “Rocket Stability Questionnaire” into the computer program
           to determine if your rocket is stable or not. If it is not stable, you must go back and
           change your rocket design to make it stable!
           You will not be allowed to launch an unstable rocket.

STEP 11.   Submit your final rocket WITH evidence that your design is stable to your instructor
           for your final progress / acceptance stamp AND GRADING of your rocket.

STEP 12.   LAUNCH!

          How To Determine Your Rockets Apogee?
               Use Trigonometry of a Right Triangle!!!




                          c                a = Apogee of
                                               Rocket




                     ooo

                    b = x meters (distance from launch pad)

Tangent 0 =     side opposite 0 = a
              side adjacent to 0 = b

IF x = 50 meters, then:

tan 0 = apogee of rocket
           50 meters

apogee = (tan 42 ) (50 meters)

apogee = (0.90) (50 meters)
apogee = 45 meters
                                                                                                  Page 12

Q8.     Determine the momentum of your rocket during its flight up. (show your calculations)

Q9.     Make a drawing of the rocket’s flight beginning at the launch pad. Using the drawing to help explain
        where the greatest AND least amount of Potential Energy existed during the flight of the rocket.
        Be sure the explain WHY it is so.

Q.10.   Using the same drawing from Question #9, explain where the greatest AND least amount of Potential
        Energy existed during the total flight of the rocket. Be sure to explain WHY it is so.

Q11.    Did your rocket perform as your team planned that it would? (Type a 50 word explanation of your
        observations. A “yes” or “no” answer is not acceptable)

Q12.    Identify 3 things that your team could have done to the design/preparation of your rocket that would
